Key result
The K4b2 metabolic system reliably assesses metabolic cost during submaximal walking, with gross measures (ICC >0.85) demonstrating greater reliability than net measures.
Why the study?
What is the test-retest reliability and minimum detectable change for oxygen consumption, gait efficiency, and heart rate using the K4b2 device during submaximal walking in healthy young adults?
Observational (n=22)

Supports K4b2 use for gross measures in healthy adults; leaves open validation in clinical populations.
Darter et al. (2013) conducted an observational in Healthy adults (n=22). K4b2 metabolic system was evaluated on Test-retest reliability (ICC) and minimum detectable change (MDC) for VO2, GE, and HR (ICC >0.85). The K4b2 metabolic system reliably assesses metabolic cost during submaximal walking, with gross measures (ICC >0.85) demonstrating greater reliability than net measures.
